Abstract:
Objective:To explore the association between sleep quality, sleep duration with blood pressure in primary and secondary school students with different nutritional status, so as to provide a reference for targeted intervention measures.
Methods:By using stratified cluster random sampling method, a total of 10 871 students aged 7 to 18 years were selected from 36 primary and secondary schools in 6 counties of Yangzhou from October to November 2023. Physical examination and questionnaire survey were conducted respectively. Student Health Status and Influencing Factors Questionnaire was used to collected basic information. The overweight/obesity and sleep quality of primary and secondary school students were determined according to the Screening for Overweight and Obesity among School age Children and Adolescents and the Pittsburgh Sleep Quality Index scale. The χ 2 test was used to compare the prevalence of elevated blood pressure in different groups of primary and secondary school students. Multivariate Logistic regression model was used to explore the association between sleep and blood pressure in primary and secondary school students.
Results:The prevalence of elevated blood pressure among primary and secondary school students in Yangzhou was 13.86 %, higher among boys (15.13%) than girls (12.62%) ( χ 2=14.30, P <0.01). The elevated blood pressure rate of obese and overweight primary and secondary school students were 26.98% and 14.90%, respectively, higher than 8.71% of non overweight and obese children ( χ 2=482.58, P <0.01). There were statistically significant differences in elevated blood pressure rate among primary and secondary school students in different sleep quality and sleep duration ( χ 2= 8.45, 71.58, P <0.05). After controlling for gender, residence, educational stage, parental education, sedentary time, the results of multiple Logistic regression analysis showed that no correlation between sleep quality and elevated blood pressure under different nutritional status was found among primary and secondary school students. In primary and secondary school students with obesity, prevalence of elevated blood pressure was higher among those with sleep duration <8 and 8 to <9 h/d ( OR=1.54, 1.72, P <0.05). However, there was no significant association found in the other groups ( OR=1.04-1.28, P >0.05). In gender stratification, sleep duration < 8, 8 to <9 and 9 to <10 h/d of obese boys were positively correlated with elevated blood pressure ( OR=1.97, 2.09, 1.86, P <0.05).
Conclusion:Among obese primary and secondary school students, sleep duration <9 h/d is associated with an increased risk of elevated blood pressure, especially among obese boys.
